The expectant mum is in the South of France for the Cannes Lions International Festival of Creativity and she was a guest speaker at the Sudler Forum, accompanied by her mother Kris Jenner.

Kim touched down at Nice airport yesterday in a striking nude bra top, but opted for more modest attire at the professional event today.

The reality star (35) opted for a Balman pinstripe two piece from the high fashion brand's Autumn/Winter collection, once again shunning traditional maternity ensembles in favour of couture.
